The Raspberry Island Lighthouse in the Apostle Islands National Lakeshore near Bayfield Wisconsin.

It is said to be one of the few surviving wood framed lighthouses left on Lake Superior. The complex includes a square tower rising up from the attached Lighthouse keeper's quarters, a brick fog signal building, frame barn, brick oil house, boathouse, two outhouses, and a dock.
The light was automated in 1947 and was later transferred to the National Park Service as part of the Apostle Islands National Lakeshore. It was added to the National Register of Historic Places in 1977. The original Fresnel lens is on display at the Madeline Island Historical Museum.
The old battery system in the fog signal building was replaced by a solar powered 300 mm Tideland Signal acrylic optic atop a pole, which continues to light the island to this day. The location is an active aid to navigation, with a characteristic white flash every 2.5 seconds.
